Frequently Asked Questions

Do you have any questions about our products and how to use them? We have compiled the most frequently asked questions and answered them. If your question is not listed here, please contact us.

  • What information is needed for custom machine knives?

    Share your application, material type and thickness, cutting method, target cut quality, and blade dimensions (or a sample). Drawings and photos help us recommend geometry and material faster.

  • Which materials are commonly used for machine knives?

    Tool steels are widely used for a balance of toughness and wear resistance. Carbide options are selected when maximum wear life and edge stability are required.

  • Can you support trial orders before volume supply?

    Yes. We support small-batch trials to verify fit and performance before repeat purchasing.

  • How do you control edge consistency and dimensional stability?

    We control heat treatment and grinding processes, then verify key dimensions and edge condition through inspection before packing.
